What is the function of beam steering in phased array systems?

The function of beam steering in phased array systems is to direct the ultrasonic beam at different angle configurations. This is achieved by adjusting the timing of the signals sent to the individual elements of the array. By carefully controlling the phase of the signals, the system can create constructive interference in specific directions, effectively steering the beam to target areas of interest within the inspected material. This capability allows for enhanced flexibility in inspection, enabling the technician to inspect various angles or positions without physically moving the transducer, thus increasing the efficiency and effectiveness of nondestructive testing. The ability to steer the beam is fundamental to the operation of phased array systems, as it maximizes the system's ability to detect flaws in different orientations.
